0116c49d5b Bug 1479035: Part 2 - Get rid of PRThread to nsThread map. r=erahm 
These maps hold strong references which complicate nsThread lifetime handling
considerably, and only have a couple of fringe uses. We have a linked list of
active threads that the thread manager can use for its internal enumeration
purposes, and the external uses are easily done away with, so there doesn't
seem to be much reason to keep the map around.

a6edc4f204 Bug 1479035: Part 1 - Don't create event queues for stub nsThread wrappers. r=froydnj 
Most of the times when we automatically create nsThread wrappers for threads
that don't already have them, we don't actually need the event targets, since
those threads don't run XPCOM event loops. Aside from wasting memory, actually
creating these event loops can lead to leaks if a thread tries to dispatch a
runnable to the queue which creates a reference cycle with the thread.

Not creating the event queues for threads that don't actually need them helps
avoid those foot guns, and also makes it easier to figure out which treads
actually run XPCOM event loops.

afec91a1db Bug 1459212 - Save memory reports for use in crash reports when low on memory r=dmajor,mccr8 
This moves the code that detects very low memory scenarios and grabs memory
reports from the main thread event-loop to the available memory tracker.
Besides removing the overhead of the check from the event-loop code this
increases the likeliness of the reports being gathered by sampling at a
higher frequency but only when we already detected a low-memory scenario. Last
but not least this add checks for low commit-space detection alongside low
virtual-memory detection.
